So I would like to get another betta and was wondering if a 5 gallon would be fine if divided with proper care? Also if anyone has a 5 gallon divided could you post a pic, I kinda wanna get the image on how big it would be. I know of course it would be 2.5 gallons but I just wanna see how it looks.

I made the divider. If you do a search for 'diy divider' you'll find it. It's really easy...just made from plastic mesh and report binders. You can find everything at Walmart for just a couple dollars.
